Answer:

Step-by-step explanation:

To find the total number of text messages sent per month by the 23 million people aged 13-17 in the United States, we can multiply the average number of text messages per person (800) by the number of people (23,000,000):

Total number of text messages = 800 text messages/person/month x 23,000,000 people

Total number of text messages = 18,400,000,000 text messages/month

To express this number in scientific notation, we can move the decimal point 10 places to the left, since there are 10 digits to the right of the decimal point:

Total number of text messages = 1.84 x 10^10 text messages/month

Therefore, the total number of text messages sent per month by the 23 million people aged 13-17 in the United States is approximately 1.84 x 10^10 text messages.

Answer:

$47.7

Step-by-step explanation:

You first have to find how much of 53 is 10%:  53/10 = 5.3  53-5.3= 47.7

Applying the angle relationships, the measures are: 1. m<A = 18°; m<B = 40°; 2. m<A = 9°; m<B = 43°; 3. m<C = 123°; m<D = 158°; 4. m<C = 131°; m<D = 160°

The position of the angle relationships in the image shown will determine the measures of the angles involved.

Therefore, we have the following for Figure  A:

1. m<D = 162°; m<C = 122°

m<A = 180 - 162 = 18° [the angle relationship is linear pair]

m<B = 180 - 122 - 18 = 40° [triangle sum theorem]

2. m<D = 171°; m<C = 128°

m<A = 180 - 171 = 9° [the angle relationship is linear pair]

m<B = 180 - 128 - 9 = 43° [triangle sum theorem]

3. m<A = 22°; m<B = 35°

m<C = 180 - 22 - 35 = 123° [triangle sum theorem]

m<D = 180 - 22 = 158° [the angle relationship is linear pair]

4. m<A = 20°; m<B = 29°

m<C = 180 - 20 - 29 = 131° [triangle sum theorem]

m<D = 180 - 20 = 160° [the angle relationship is linear pair]

Therefore, we have the following for Figure  B:

9. m<A = 65° [given]

m<B = 180 - 65 = 115° [linear pair]

m<C = 65° [corresponding angles]

m<D = m<B [corresponding angles]

m<D = 115°

m<E = m<C = 65° [vertical angles]

m<F = 180 - 65 - 90 = 25

10. m<A = 70° [given]

m<B = 180 - 70 = 110° [linear pair]

m<C = 70° [corresponding angles]

m<D = m<B [corresponding angles]

m<D = 110°

m<E = m<C = 70° [vertical angles]

m<F = 180 - 70 - 90 = 20

11. m<F = 22° [given]

m<E = 180 - 90 - 22 = 68°

m<E = m<C = 68° [vertical angles]

m<A = m<C = 68° [corresponding angles]

m<B = 180 - 68 = 112° [linear pair]

m<D = m<B = 112° [corresponding angles]

FIFO Method:

1. Determine the cost of the oldest inventory items available for sale (i.e., the items purchased first.

2.Multiply the cost per item by the number of items sold to determine the COGS.

3.Subtract the COGS from the total cost of the oldest inventory items to determine the value of the last inventory.

LIFO Method: The only difference between FIFO and LIFO method is that in LIFO method, newest inventory cost and value are determined in the first and last step respectively.

The average cost method is a way of determining the cost of inventory by taking the average of the cost of each item in the inventory. FIFO and LIFO are two other methods of determining the cost of inventory.

Average Cost Method:

Determine the total cost of all inventory items available for sale.

Determine the total number of inventory items available for sale.

Divide the total cost of inventory by the total number of items to get the average cost per item.

Multiply the average cost per item by the number of items sold to determine the cost of goods sold (COGS).

Therefore, the recursive formula for the population growth model is:

[tex]P_n = 0*P_n-1[/tex] And the explicit formula for [tex]P_n[/tex] is:

[tex]P_n = 80*(1+0) n\\P_n=80[/tex]

The exponential growth model is a mathematical function that describes the growth of a population or system over time, assuming that the rate of growth is proportional to the size of the population or system. In other words, the model assumes that the growth rate of the population or system increases as the population or system grows larger.

by the question.

To find the recursive formula for the population growth model, we need to use the equation:

[tex]P_n = r*Pn-1[/tex]

where [tex]P_n[/tex] represents the population size at time n, Pn-1 represents the population size at the previous time step (n-1), and r represents the growth rate.

Given that the population grows exponentially with Po = 80, we can use the formula:

[tex]P_n = Po *(1 + r)n[/tex]

where Po is the initial population size and n is the number of time steps.

Using the fact that [tex]P_1 = 80[/tex], we can solve for the growth rate r:

[tex]Pq = Po * (1 + r)1\\80 = 80* (1 + r)1\\1 + r = (80/80)^(1/1)\\1 + r = 1^(1/1)\\1 + r = 1\\r = 0[/tex]

The total cost for one admission and r rides is $10 for admission and $2 multiplied by r for the rides, which can be expressed as the formula: Cost = $10 + $2r.

The problem statement provides two pieces of information: the admission cost and the ride cost. We are asked to find the total cost for one admission and r rides.

The admission cost is straightforward - it is a fixed cost of $10. This means that regardless of how many rides you go on, you will always pay $10 just to get into the fair.

The ride cost is based on the number of rides you go on. Each ride costs $2, so if you go on r rides, you will pay $2 multiplied by r, or 2r, for the ride portion of the cost.

To find the total cost for one admission and r rides, we simply add the admission cost of $10 to the ride cost of 2r, which gives us the formula:

Cost = $10 + $2r

This formula tells us that the cost of one admission and r rides is equal to $10 plus $2 multiplied by the number of rides (r) that the person goes on.

Applying equations, the number of each type of pancake are originally: 81 blueberry pancakes, 27 plain pancakes, and 42 chocolate chip pancakes.

Let's use the following variables to represent the number of each type of pancake:

From the problem statement, we know that:

x + y + z = 150 (total number of pancakes)

1/3 x blueberry pancakes are left

4/5 y plain pancakes are left

1/2 z chocolate chip pancakes are left

There are now an equal number of each type of pancake

From the last statement, we can set up the following equations:

1/3 x = y = 1/2 z

Multiplying all sides of each equation by the least common multiple of the denominators, we get:

2x = 6y = 3z

Dividing all sides of each equation by 2, we get:

x = 3y = 3/2 z

Now we can use the equation x + y + z = 150 to substitute for x in terms of y and z:

3y + y + 2/3(3/2z) = 150

Simplifying and solving for z, we get:

5z = 270

z = 54

Substituting z = 54 into x = 3/2 z, we get:

x = 81

Substituting z = 54 into y = x/3, we get:

y = 27

Therefore, there were originally 81 blueberry pancakes, 27 plain pancakes, and 42 chocolate chip pancakes.

Therefore, the angle of depression from Lisa's line of sight to the cat is approximately 12.21 degrees.

An angle is a geometric figure formed by two rays (or line segments) that share a common endpoint, called the vertex. The rays are also called the sides or legs of the angle. Angles are usually measured in degrees, with a full circle measuring 360 degrees. Angles are used to describe the direction of an object, the orientation of a shape, or the position of a line. They are also used in trigonometry to calculate distances and heights in triangles, and in many other areas of mathematics and science.

Here,

In the diagram above, we have Lisa standing at point L and looking out the window of the building at her lost cat at point C, which is 58.5 meters away from the building. The height of the window from the ground is 12.6 meters. Let's call the angle of depression from Lisa's line of sight to the cat as ∠WLC. To find this angle, we need to use the tangent function, which relates the opposite side (12.6 meters) and adjacent side (58.5 meters) of ∠WLC.

tan ∠WLC = opposite / adjacent

tan ∠WLC = 12.6 / 58.5

Using a calculator, we get:

∠WLC = tan⁻¹(12.6 / 58.5)

∠WLC ≈ 12.21 degrees
